(from General
Motors Press Release) The Chevy
Suburban HD Z71 is the culmination of a what if exercise that
melds the popular Suburban 2500HD with the popular Z71 off-road
package a combination not currently offered by the factory and
partners it with a new, fuel-saving smaller-displacement diesel
engine. The concept uses many production parts, including the
front-end assembly from Chevys HD trucks, along with some unique
custom touches including rear wheel flares that pick up the
styling cues of the front end. Power is generated by a new 4.5L
diesel engine that gives this off-road-ready Suburban power, poise
and efficiency.
